No need to check for rotation in Space, as Body#resistive_torque will check that.
Disable printing rotations while applying resistive torque.
Apply additional centripetal force for tighter turning.
Remove unnecessary variable 'u' as '@u_axis' exists.
Separate locomotion blender into it's own file.
Remove unnecessary commented out code.
Rotate character around by locking angle to velocity vector, and using only forces.
Snap angle of body if close enough to prevent jitter.
Refactor determining direction of rotation force.
Compute rotation force in a method, so key values can be set.
Use #between? instead of manually doing that logic.
Increase snap margin for body angle.
Calculate radial and tangential components of movement force in separate methods for increased clarity.
Note that movement should not depend on both body angle and velocity.
Turn faster while moving slower.
Create physics contstants for movement directions, as well as movement threshold.
Create new file for animation unit conversions.
Scale lizard down to a more managable size.
No need to check for rotation in Space, as Body#resistive_torque will check that.
